The first 3 TVs were a huge let down, and this big screen 4K tv ended up being a let down as well. I was excited in the video not to see much banding, but as I watched some shows on Netflix and played a couple of Xbox One games, I noticed terrible light leakage on both sides of the screen.

I went to 5 TV stores and ran the same banding test on LG & Samsung screens and found the same amount of banding and general lack of screen uniformity on the display models.

Comment if you have a big screen whether or not you've found similar issues with banding/dirty screen, lack of uniformity or light leakage.
